It's still the same idea at the core, but adaptations really have to, well, adapt depending on where they're being portrayed and who's portraying them. And he also pointed out how Mark's Epiphany is more obvious? As coming out as gay in the American version.I forgot what exactly he said, but, having seen both, I agree, mainly because it's more of a cultural thing I think? I don't really want to discuss differences in LGBT in the US vs Japan here because I don't think I'm informed enough as someone not from either country lol, but it really had a different feel. In the Japanese version, they made the band seem cooler, like idols as he said. The original was from 2005 (thanks to for this information!), and he did point out it was supposed to be like 90s boy bands like Backstreet Boys (which is true lol it's kind of a parody of boy bands and Christian bands).
He was discussing how Altar Boyz in Japan has a different feel compared to the original American production.
Oyama Masashi did another IG live earlier and he touched on a topic I find really interesting.
